Randomized trial examines fish assemblage and seagrass effects from jetty density in coastal estuaries, suggesting habitat trade-offs.

This research aims to understand how private jetties and their density affect fish assemblages and seagrass in a temperate estuary.
Quantified fish assemblages using remote underwater video systems and remotely operated vehicles.
Compared metrics among control, low-density (≤6 jetties per 150 m), and high-density (≥10 jetties per 150 m) treatments.
Jetty sites altered fish assemblage composition, leading to greater species diversity and abundance.
Seagrass cover and canopy height decreased near jetties at two out of three locations.
Both low- and high-density jetty treatments showed complex and inconsistent responses across locations.

Smith et al. (2026) studied this question.
